A GUN ????

A week ago my Brother and I took some pictures of a BMW 645ci (you can find them here) with our cell phones while passing next to it in Tabaris.
When we downloaded the pictures on the computers my brother found something strange in two of those pictures, A guy in the backgrond pointing what appeared to be a gun in our direction!!! Since the pictures are not very clear this can be a cell phone also taking pictures of the car so what do you think.
